SQL92 says
ii) If the <fetch orientation> implicitly or explicitly spec-
ifies NEXT, specifies ABSOLUTE or RELATIVE with K greater
than N, or specifies LAST, then CR is positioned after the
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
last row.
^^^^^^^^
So as far as the ending cursor position is concerned, LAST agrees with
ALL. It looks to me like the SQL definition only contemplates returning
a single row, but it's less than clear *which* row they mean for LAST.

Sure. FETCH n in Postgres has always corresponded to FETCH RELATIVE n.
